TYPE-WRITING MACHINE.

To all whom it may concern:

Be it known that I, AUGUSTUS G. SNYDER, a citizen of the United States,and resident of Ilion, in the county of Herkimer and State of New York,have invented certain new and useful Improvements in Type- WritingMachines, of which the following is a specification.

My invention relates to typewriting machines, and more particularly totype bar and hanger constructions for use in visible or front-strikemachines and to the manner of mounting the hangers in the machine.

One object of my invention is to provide a comparatively simple andefficient construction in which wide bearings may be provided for thetype bars and yet a large number of type bars may be assembled in avisible machine without liability of conflict and without undulycrowding the type bars.

Another object of my invention is to provide comparatively simple andefiicient means for adjusting the bearings of each i type bar and toarrange the adjusting means so that access may be readily gained theretowithout dismounting parts of the construction.

A further object of my invention is to arrange the securing means forthe hangers in such a manner that access may be readily gained theretofrom the front of the machine at any time without disconnecting any ofthe parts so that one or more of the individual hangers may be removedwhen desired.

Another object of the invention is to provide constructions such asthose referred to with means whereby a ready adjustment of the hangersis afforded.

A still further object of the invention is to so construct and arrangethe parts that the segment constitutes a dust guard or shield for thetype bar bearings.

To the above and other ends which will hereinafter appear my inventionconsists of the features of construction, arrangements of parts andcombinations of devices to be hereinafter described and claimed.

In the drawings, wherein like reference characters indicatecorresponding parts in the various views, Figure 1 is a fragmentaryvertical sectional view, taken centrally Specification of LettersPatent.

place; the platen being shown diagrammatically. Fig. 2 is a front viewshowing most of the parts illustrated in Fig. l with the entire systemof hangers and a single type bar in place, said type bar and the topplate being shown in section. Fig. 3 is a detail rear view of thesegment with two hangers in place thereon. Figs. 4 and 5 are detailviews showing a hanger of one set and the pivotal end of thecorresponding type bar, and Figs. 6 and 7 are detail views showing ahanger of the other set, the pivotal end of the corresponding type barbeing shown in Fig. 6.

My invention relates more particularly to a visible typewriting-machine, and in the present instance I have illustrated it inconnection with a front-strike machine. The top plate 1 of the machineis mounted on corner posts 2 and a type bar segment 3 is connected tothe top plate by an angle iron or bracket a situate-d centrally of themachine and secured to the top plate by screws 5 and connected to thesegment by screws 6. This angle bracket constitutes the sole support forthe segment and it will be seen that the segment is detachably supportedso that the type bars and hangers may be mounted in place on the segmentoutside of the machine and introduced as a whole into the machine. Thetype bar segment which opens upwardly and has the general form of thesection of a cone, its inclination being downward toward the front ofthe machine, and it is stepped on its rear or under side, one step 7constituting a bearing for the hangers 8 of the rear series, whereas thestep 9 constitutes a bearing for the forward series of hangers 10. Froman inspection of Fig. 1 it will be observed that p U the hangers aredisposed ininclined planes. the hangers extending downwardly andforwardly from the upper ends thereof, and that each fore and aft pairor set of hangers are arranged nearly 'in parallel planes, as indicatedin Fig. 1.

The bearing surface for each hanger is preferably formed as a facet soas to provide a flat bearing for the associated hanger, each facet ofthe step 7 being indicated at 7 whereas each facet of the step 9 isindicated at 9 in Fig. 3. The hangers of the rear set are constructed asshown in Figs. 1, 4 and 5 of a block-like hanger body 11 having a tappedopening 12 therein for cooperation with the threaded end of a securingscrew 13 which passes downwardly from the top of the segment through anelongated opening 14 therein, the head of the screw extending at aninclination toward the front of the machine as shown in Figs. 1 and 2where access may be readily had to the screws from above while standingin front of the machine. The opening 14 is of such dimensions as toafford an adjustment of the screw 13 and hanger 8 along an element ofthe cone of which the segment is a part, whereby the distance of thetype bar pivot from the printing point may be regulated. A countersunkopening 14 is preferably provided in the front face of the segment ateach opening 14 for the reception of the head of the securing screw 13and this countersunk opening is also elongated to afford a bodilyadjustment of the screw. A second series of openings 15 extend throughthe segment forward of the openings 14 and are staggered relativelythereto. The openings 15 are like the openings 14 except that the formerare not countersunk but they are elongated radially to afford a bodilyradial adjustment of the screws and the forward set of hangers 10 whichthey secure in place. Each hanger 8 and each hanger 10 is bifurcated at16 to provide bearing arms 17, and each hanger also has a longitudinalslot 18, the plane of which includes the type bar pivot. Said slot 18cuts lengthwise through each of the arms 17 and back into the bodyportion of the hanger, terminating in an enlarged opening 19.

An adjusting rivet or screw 20 takes into the body of the hanger at thedivided portion thereof but back of the bearing arms so as to effect anadjustment of the bearing type bars 22. Thus the screw 20 of each hangerpasses freely through a hole 2O (see Fig. 7) in the hanger at one sideof the slot 18 and is threaded into the tapped portion of this hole atthe other side of the slot as shown in Fig. 5; so that a tightening ofthe screw compresses the hanger arms 17 and a loosening of the screwaffords a separation of said arms. The adjusting screw 20 of each hangeris in the median line of the hanger arm 17 as shown in Fig. 4 so thatthe pressure exerted by this screw may be equally distributed on thefour sections constituting the hanger arms. As shown in the presentcase, all of the hangers 8 of the rear set are alike and all the hangers10- of the forward set are alike. A hanger of the forward set is shownin detail in Figs. 6 and 7 and is constructed the same as the hangers 8,except that it is shorter and the securing screw passes through anopening 123a part only of which is in the unsplit or solid portion ofthe body of the hanger. The securing screws for the short hangers arenot long enough to extend past the slot 18, so i that the pressureapplied to the securing screws does not interfere with the adjustment ofthe hanger or bearing arms effected through an adjustment of the screw20, no matter how hard the securing screw 13 may be tightened.

It will be observed that the hangers are secured in place on the segmentby means which are entirely independent of the screws 20 which effectthe relative adjustment of the hanger arms and that therefore theadjustment of the hanger arms is in no manner affected by the securingmeans. The pivots of the type bars are preferably made conical at theirends, and suit-able recesses are formed in the hangers to receive saidpivots. The construction is such that the screws 20 are adapted totighten the bearings about the pivots. The enlarged open ings 19 add tothe flexibility of the hanger at the end of the slot 18; and said slotsdivide the arms 17 from and through the free ends thereof, back into thebody portion of the hanger.

From an inspection of Figs. 1 and 2 it will be seen that the adjustingscrews 20 for the forward set of hangers are arranged with their headsextending forwardly into recesses 20 formed in the type bar segment andare situated in a position where access thereto may be readily obtainedfrom the front of the machine in order to effect an adjustment of thebearing arms of the front set of hangers when desired. The heads of thescrews 20 of the rear set of hangers 8 are at the rear or under side ofthe segment, yet these screws are so situated that access thereto may behad wit-h little difficulty. Fig. 1 shows two adjacent type bars, one ofeach set, and from an inspection of said figure it will be observed thatthe pivots 21 of these two type bars are arranged in a plane indicatedby the dotted line a which is nearly at right angles to the line I)drawn from a type on one of the associated type bars to the printingpoint. By this arrangement of the pivots the forward ends of the typebars are arranged in their normal positions substantially in transversealinement, notwithstanding the fact that the type bars connected to theforward set of hangers are shorter than those connected to the rear setof hangers.

From an inspection of Figs. 1 and 2 it will be seen that the openings 14and 15 in the segment through which the securing screws pass from thefront of the machine, and the securing screws themselves have astaggered arrangement and that the type bar hangers are likewisearranged in staggered relation, the type bar hangers of the two setsoverlapping in fore and aft radial planes. Each of the type bars ismounted to swing upwardly and rearwardly to strike against the frontface of a platen 23 and each type bar has connected thereto at 24 a pulllink 25 which is connected to any suitable actuating means by which thetype bar is swung to the printing point. .The forward ends of the typebars normally rest on a segmental pad or type rest 26. It will also beobserved from an inspection of Fig. 1 that the type bar segment of thisconstruction is interposed between the pivot bearings of the type barsand the printing point or line and that it therefore constitutes a dustguard or shield to prevent any dust or grit which drops from the frontface to the seg ment from entering the pivot bearings of the type bars.

Various changes may be made in the details of construction andarrangement with out departing from my invention.
